AUSTIN (KXAN) — Former Pedernales firefighter Joe Carr, sentenced to 60 years in prison in February of 2014 for killing his fiancée Veronica Navarro, has lost his appeal.

Carr claimed that the evidence against him was insufficient to show that he tampered with evidence or committed the murder, that the trial court “abused its discretion by admitting and excluding evidence” and that the trial court also abused its discretion by denying his motion for a new trial.

Navarro, Carr’s 22-year-old fiancée, was last seen alive or heard from by any witness on June 27, 2011, according to court documents. Her decomposing body was found submerged in Lake Travis on July 6, 2011, wrapped in a Coleman tent, bound by rope and secured to cinder blocks and paint cans.

There was no eyewitness testimony of how she died and ended up in the lake near Pace Bend Park, the documents continue.
